Title: Structure of magneto-optical recording medium
Inventor: KIRINO FUMIYOSHI
IPC: G11B11/105
Filed: 1990-06-15
Abstract: PURPOSE:To obtain a large magneto-optical effect by utilizing the multiple interference of light and to allow ultra-high-density optical recording by using films formed with distributions of optical complex indices of refraction in a thin film direction. CONSTITUTION:The multilayered film layers 2 alternately laminated with Pt and Co are formed on a substrate 1 and a Tb27Fe58Co12Nb3 film is formed as a rare earth/transition metal element film 3. The multilayered films 2 alter nately laminated with the Pt and Co of the same constitution as the constitution of the 1st layer are again formed thereon to constitute the magneto-optical recording film. The apparent refractive index is changed by the film thicknesses of the respective layers of the Pt and the Co in this case. The thickness of the Pt near both boundaries of the recording films is increased and the thickness of the Co in the intermediate position is increased. The magneto-optical effect is improved by the multiple interference effect of light within the recording films in this way.

Abstract: PURPOSE:To prevent forgery or forging by providing a switch for detecting a fact that a case of a read/write device of a magnetic card is closed, and cutting off an electric power source of a memory when the switch is opened, so that read and write cannot be executed. CONSTITUTION:When a power source is turned on to a magnetic card read/ write device, an ROM1 is started, a CPU2 checks the contents of a specified address of an RAM3 in accordance with a program stored in the ROM1, and when a normal data is stored, the CPU2 delivers a control right to the RAM3. Thereafter, the CPU2 gives an indication to an input/output selecting circuit 4 in accordance with an executing program stored in the RAM3, selects the magnetic card read/write device 5, and reads or writes a data of the RAM3 in accordance with a read/write signal. Usually, as for the RAM3, the contents are protected by a backup power source 6, but when a case is opened, a switch 7 is opened, and the contents are broken down. In this way, an illegal act is prevented.

Abstract: PURPOSE:To increase a substantial capacity density and control charging with ease and make very quick charging possible with a large current flow by making a cadmium magnetic plate contain stannic oxide at a specific rate to a total quantity of cadmium. CONSTITUTION:A charging efficiency before cadmium hydroxide is generated when a cadmium negative plate mainly composed of cadmium hydroxide or cadmium oxide and metallic cadmium as active material is charged by an electric current of 1CA on the basis of a theoretical capacity of cadmium oxide or cadmium hydroxide is approx. 93%; however, when stannic oxide is contained at 0.5-20wt.% of a total quantity of cadmium, the charging efficiency increases to approx. 98%. If a change in potential made until generation of hydrogen at a charging time is detected as a change in terminal voltage by use of this negative plate having a good charging efficiency, charging control is easy, and if a constant voltage is set at that point of time, a current flow becomes small in an overcharge region, so that an alkaline secondary battery capable of a quick charge and also free from loss of electrolyte is produced.

Title: Method for measuring degree of alloy formation of galvannealed steel plate
Inventor: FUJINAGA TADAO
IPC: G01N23/207
Filed: 1982-09-08
Abstract: PURPOSE:To measure the degree of alloy formation nondestructively, continuously, and accurately, by measuring an X-ray diffraction intensity ratio or a peak area ratio on respective specific diffraction grating surfaces of remaining Zn and an alloy formation phase of a galvannealed steel plate surface, which is obtained by the alloying process of a fused zinc galvanized steel plate. CONSTITUTION:The X-ray diffraction intensities in a diffraction grating surface eta (101) of the remaining Zn in a galvannealed steel plate and a diffraction grating surface delta1(101) of an alloy formation phase (FeZn7) are detected. Then the degree of alloy formation is obtained from the intensity ratio Ieta/Idelta1 or the area ratio SIGMAIeta/SIGMAIdelta1. The degree of alloy formation can be measured accurately, stably, nondestructively, and continuously in comparison with the following conventional metod for the same steel plate: tacky tape is stuck on a galvannealed steel plate, whose intensity area ratio is, e.g., in the range of 0.25-0.5, then the tape is separated, and pass or fail is determined by the amount of attached Zn powder. Thus the degree of alloy formation is accurately controlled and the yield rate of products is improved.

Title: Control device for continuously variable transmission having clutch
Inventor: KORI YASUO
IPC: F16H9/00
Filed: 1994-06-16
Abstract: PURPOSE:To enable a departure of a vehicle, and prevent a belt slip at traveling time by controlling engagement of a clutch according to a synchronous time estimate estimated from clutch output shaft rotating speed when abnormality is detected by an engine rotating speed detector. CONSTITUTION:When a shift range is put in a travel possible position, it is judged that an accelerator is turned on by a signal from an accelerator ON-OFF condition detector 14, and when abnormality is detected by an engine rotating speed sensor 11, synchronous time clutch output shaft rotating speed is estimated by referring to a prescribed map from rotating speed of a rotating speed detecting sensor 12 of a drive pulley 4. This estimate is compared with actual output shaft rotating speed, and when the output shaft rotating speed is not more than the estimate, clutch pressure is controlled as a function of throttle opening and time. When the output shaft rotating speed is not less than the estimate, it is judged as a synchronous condition, and clutch control pressure is maximized, and a clutch is directly coupled, and next, a speed change ratio of the pulley is controlled so that pressing force to a driven pulley becomes maximum pressure to a given speed change ratio.

IPC: H01F10/08
Filed: 1989-06-19
Abstract: PURPOSE:To achieve high durability and permeability and improve saturation magnetic flux density by alternately laminating layers of iron carbide and layers of iron carbonitride. CONSTITUTION:Layers of iron carbide whose C concentration is 3-35 in mole percentage and layers of iron carbonitride whose N concentration is 0.2-15 in mole percentage are alternately laminated and the thickness of single layer of iron carbide is set to 0.5-1000nm and the thickness of single layer of carbonitride is set to 0.5-300nm. Argon gas introduced into a reaction chamber 41 from an argon bomb 43 is brought into plasma state by the energy of radio wave supplied to between electrodes 46 from a high frequency power supply 45 to sputter a iron carbide alloy target 47. The iron carbide sputtered makes an iron carbide film 11 by reaching a substrate 48 consisting of a material such as ceramic. In this process, when a characteristic amount of nitrogen gas is introduced into the reaction chamber 41 from a nitrogen bomb 44, a magnetic film formed on the substrate 48 becomes iron carbonitride 12. At that time, a multilayer film of iron carbide 11 and iron carbonitride 12 with arbitrary thickness can be formed without replacing the target 47 by controlling the time interval and the number of times for introducing the nitrogen into the reaction chamber 41 from the nitrogen bomb 44.

Abstract: PURPOSE:To prevent the unnecessary deposition of substrate metal in a magnetic gap and to put a sendust alloy in practical use by providing a recessed part to store a soldering material to the joining surface of a core block, and forming an Ag layer on the inner surface of the recessed part as a substrate. CONSTITUTION:A recessed part 25 for storing molten Ag solder 24, a soldering material, is provided to core blocks 12 and 16. Besides, a thin substrate Ag layer 26 having several mum thickness is formed on the inner surface of the recessed part 25 of the ''Sendust(R)'' core blocks 12' and 16', when the cores are joined. Then the blocks 12' and 16' are closely joined by a pinching jig. An Ag solder round bar is inserted into said recessed part, and heated to join the blocks. Since the Ag layer 26 is formed as a substrate in this way, unnecessary deposition of the substrate metal in a magnetic gap (g) is eliminated, and insufficient formation of the gap is prevented. Consequently, a ''Sendust(R)'' alloy having a problem in joining can be favorably put in practical use.
